I installed this theme on a charity website that I was working on, and it works great. I had a problem that ended up not being the fault of Museum Core, and Chris was super helpful and quick to respond. I will definitely continue to use this them and look into using more Museum themes.
Few bugs in first install, but these seem to have been cleared by the latest update. Very flexible theme which lends itself readily to customization. Also had a couple of issues to resolve and Chris was more than helpful with them. I recommend this theme without reservation.
